Answer:
1.78 × 10²⁶ Atoms
Explanation:
Relation between number of molecules and moles is,
No. of Molecules = Moles × 6.022 × 10²³ Molecules/mol
No. of Molecules = 99 mol × 6.022 × 10²³ Molecules/mol
No. of Molecules = 5.96 × 10²⁵ Molecules
Also, In CO₂ Molecule there are 3 atoms.
So,
No. of atoms = 5.96 × 10²⁵ Molecules × 3
No. of atoms = 1.78 × 10²⁶ Atoms
Answer:
4.42x10⁻¹⁹ J/molecule
Explanation:
At a double bond, there's sigma and a pi bond, and at a single bond, there's only a sigma bond. Thus, if the energy to break both sigma and pi is 614 kJ/mol, and the energy to break only the sigma bond is 348 kJ/mol, the energy to break only the pi bond is:
E = 614 - 348 = 266 kJ/mol
Knowing that 1 kJ = 1000 J, E = 266,000 J/mol
By Avogadro's number, 1 mol = 6.02x10²³ molecules, thus:
E = 266,000 J/mol * 1mol/6.02x10²³ molecules
E = 4.42x10⁻¹⁹ J/molecule
Answer:
water cycle and carbon cycle
Answer:
these two processes supply the electrons that are needed for the electron transport chain
Explanation:
Oxidative phosphorylation is the process in which electrons transfer from electron donors to electron acceptors (usually oxygen). These reactions are called redox reactions, and they provide energy used to form ATP.
Electron donors (NADH and FADH2) used in oxidative phosphorylation are produces in some of the catabolic biochemical processes, such as glycolysis, the citric acid cycle, and beta oxidation. The NADH and FADH2 are energy-rich molecules because each of them contains a pair of electrons thus having a high transfer potential. Because of that, oxidative phosphorylation could not happen without first obtaining electron donors in glycolysis and citric acid cycle.
